IoT technology refers to the technology that connects any object to the Internet through information sensing devices, such as sensors, RFID tags, etc., to exchange information and communicate, so as to achieve intelligent management and control.

[0003] With the rapid development of IoT technology, a large number of smart devices are widely used in various fields. These devices use different communication protocols, which leads to compatibility issues when the devices are connected to the IoT platform. Traditional device access methods are often developed for specific protocols and lack flexibility and scalability. Summary of the invention

[0004] The technical task of the present invention is to provide a multi-protocol Internet of Things system and a multi-protocol Internet of Things soft gateway development method to solve the compatibility problem of different communication protocol devices accessing the Internet of Things platform.

[0005] The technical task of the present invention is achieved in the following way: a multi-protocol Internet of Things system, which includes a device layer, a soft gateway layer and a cloud-based Internet of Things platform layer. The device layer transmits TCP device messages, UDP device messages and Websocket device messages to the soft gateway layer through a protocol parsing plug-in, obtains the parsed TCP device messages, UDP device messages and Websocket device messages, and the soft gateway layer transmits the parsed TCP device messages, UDP device messages and Websocket device messages to the cloud-based Internet of Things platform layer through the MQTT protocol. The cloud-based Internet of Things platform stores and analyzes the parsed TCP device messages, UDP device messages and Websocket device messages.

[0006] Preferably, the soft gateway layer includes:

[0007] Device access module, used to communicate with devices of different protocols through multiple communication interfaces;

[0008] The protocol conversion module is used to convert the device data of different protocols into a unified data format of the cloud IoT platform through the protocol parsing plug-in, and upload the protocol conversion plug-in on demand to increase versatility;

[0009] The device management module is used to manage the devices in a unified manner, including device registration, status monitoring, fault diagnosis and configuration of communication parameters.

[0010] The data transmission module is used to upload the converted device data to the cloud IoT platform through the cloud link, and the cloud IoT platform stores and analyzes the converted device data.

[0011] More preferably, the device access module configures a cloud link in a cloud link interface to interact with a cloud IoT platform;

[0012] The functions of cloud links are as follows:

[0013] ①Upload the messages sent by the device layer to the cloud IoT platform layer;

[0014] ② Send the receipt message from the cloud IoT platform layer back to the device layer;

[0015] The device layer and the cloud IoT platform layer only establish a channel for data transmission through the cloud link.

[0016] Preferably, the device management module is used to configure the cloud device to correspond to the physical device, specifically:

[0017] Add cloud devices in the soft gateway layer and configure the communication parameters of the devices so that the cloud devices can receive messages from physical devices and communicate with the cloud IoT platform layer;

[0018] The cloud device acts as a bridge between the device layer and the cloud IoT platform layer. It verifies and converts the incoming device layer data as required, and then sends it to the cloud IoT platform layer, thus connecting the device layer and the cloud IoT platform layer.

[0019] Preferably, the protocol conversion module is used to configure the protocol parsing plug-in, specifically:

[0020] The default protocol parsing plug-in in the soft gateway layer is transparent transmission of messages. Users download the protocol parsing plug-in template and modify the device layer message processing method of the protocol parsing plug-in according to their own needs. Users debug locally, package and upload the application after debugging and modification.

[0021] The protocol parsing plug-in converts the data uploaded by the device layer according to the method in the protocol parsing plug-in. The conversion result is based on the data format required by the cloud IoT platform layer.

[0022] Among them, the soft gateway layer has multiple built-in protocol conversion modules. The soft gateway layer with modular structure is adopted in the protocol conversion process, which supports dynamic loading and unloading of protocol conversion modules.

[0023] Preferably, the data transmission module is used to simulate a real device sending a message, specifically:

[0024] The user uses the socketTool tool to simulate sending messages or uses a real device to test sending messages. The situation is as follows:

[0025] If a receipt message is set, check whether the message has been received based on the receipt message;

[0026] If the receipt message is not set, the default is to return the sent message;

[0027] If the reported message is a physical model, the IoT platform checks whether the corresponding device has received the message or whether there is a message record in the device's historical data message. The latest message sent by the device saved in the soft gateway layer is used to determine whether the communication with the cloud IoT platform layer is successful.

[0028] Preferably, the system also includes a remote monitoring and management layer, which is used to perform remote monitoring and management after receiving data at the cloud-based IoT platform layer, and to view the operating status, parameter information and fault information of the equipment in real time through the cloud-based IoT platform layer; at the same time, remote control and parameter setting operations are performed on the equipment layer.

[0030] Device access: The soft gateway layer supports multiple communication interfaces to communicate with devices of different protocols, such as Modbus, MQTT, OPC UA, HTTP, TCP / IP, etc.

[0031] Protocol conversion: The device layer data of different protocols are converted into a unified data format of the cloud IoT platform layer through the protocol parsing plug-in, and the protocol parsing plug-in is uploaded on demand to increase versatility;

[0032] Device management: The soft gateway layer manages the connected device layer in a unified manner, including device registration, status monitoring, fault diagnosis, and configuration of communication parameters;

[0033] Data transmission: The converted device layer data is uploaded to the cloud IoT platform layer through the cloud link, and the cloud IoT platform layer stores and analyzes the converted device layer data;

[0034] Remote monitoring and management layer: After receiving data at the cloud IoT platform layer, remote monitoring and management are carried out, and the operating status, parameter information and fault information of the equipment are viewed in real time through the cloud IoT platform layer; at the same time, remote control and parameter setting operations are carried out on the equipment layer.

[0035] As a preferred method, the device access is as follows:

[0036] Configure the cloud link in the cloud link interface to interact with the cloud IoT platform;

[0037] The functions of the cloud link are as follows:

[0038] ①Upload the messages sent by the device layer to the cloud IoT platform layer;

[0039] ② Send the receipt message from the cloud IoT platform layer back to the device layer;

[0040] The device layer and the cloud IoT platform layer only establish a channel for data transmission through the cloud link;

[0041] The details of device management are as follows:

[0042] Add cloud devices in the soft gateway layer and configure the communication parameters of the devices so that the cloud devices can receive messages from physical devices and communicate with the cloud IoT platform layer;

[0043] The cloud device acts as a bridge between the device layer and the cloud IoT platform layer. It verifies and converts the incoming device layer data as required, and then sends it to the cloud IoT platform layer, thus connecting the device layer and the cloud IoT platform layer.

[0044] Preferably, the protocol conversion is as follows:

[0045] The default protocol parsing plug-in in the soft gateway layer is transparent transmission of messages. Users download the protocol parsing plug-in template and modify the device layer message processing method of the protocol parsing plug-in according to their own needs. Users debug locally, package and upload the application after debugging and modification.

[0046] The protocol parsing plug-in converts the data uploaded by the device layer according to the method in the protocol parsing plug-in. The conversion result is based on the data format required by the cloud IoT platform layer.

[0047] The specific data transmission is as follows: the user uses the socketTool tool to simulate sending messages or uses a real device to test sending messages, as follows:

[0048] If a receipt message is set, check whether the message has been received based on the receipt message;

[0049] If the receipt message is not set, the default is to return the sent message;

[0050] If the reported message is a physical model, the IoT platform checks whether the corresponding device has received the message or whether there is a message record in the device's historical data message. The latest message sent by the device saved in the soft gateway layer is used to determine whether the communication with the cloud IoT platform layer is successful.

[0051] The multi-protocol Internet of Things system and the multi-protocol Internet of Things soft gateway development method of the present invention have the following advantages:

[0052] (i) The present invention introduces a soft gateway layer as an intermediate layer to achieve unified access and data conversion of devices with different communication protocols to the Internet of Things platform, improve the compatibility and scalability of the Internet of Things platform, and provide an efficient and flexible device access solution system for the Internet of Things field;

[0054] (III) The present invention supports multi-protocol device data analysis: the protocol analysis plug-in is uploaded by the user, which ensures the confidentiality of the analysis method. The user defines the specific implementation of processing device messages in the protocol analysis plug-in, which will not be leaked. Different protocol analysis packages are used to implement data processing of different protocols. One soft gateway can implement the analysis of multiple protocols.

[0055] (IV) The protocol parsing plug-in of the present invention can be dynamically updated: In addition to the built-in protocol plug-in, the soft gateway can also dynamically load and unload the plug-in uploaded by the user through the protocol conversion module, which effectively solves the hot update problem of the device message parsing plug-in. The latest parsing plug-in can be applied to parse the device message without restarting the gateway to modify the parsing plug-in; by dynamically loading and unloading the protocol conversion module, the soft gateway can flexibly adapt to the access requirements of devices with different protocols; wherein, the protocol conversion module mainly parses and loads the protocol package, loads the method in the protocol package to the local, and calls the parsing method for parsing when the message arrives; the user downloads the protocol template, implements the method therein, and then packages and uploads it. After the system receives the uploaded plug-in, it understands the parsing configuration into the system, and receives the device message, it can process the message according to the configured plug-in;

[0056] (V) The present invention is compatible and flexible: by introducing a soft gateway as an intermediate layer, the present invention is compatible with various devices using different communication protocols and realizes unified access and management of devices; with modular design, each functional module can be independently upgraded and expanded, which improves the flexibility of the system;

[0057] (VI) The present invention has confidentiality and scalability: the device message parsing method of the corresponding protocol is handed over to the user for maintenance, which to a certain extent meets the user's demand for closed message processing and has good versatility and scalability;

[0058] (VII) The present invention supports multiple protocols: the soft gateway layer supports multiple communication protocols, can achieve unified access and management of different devices, solves the compatibility problem of device access to the Internet of Things platform, and can expand the supported protocols by uploading plug-ins of different protocols as needed.
